    Five wild species of Psidium viz., Psidium cattleianum lucidum, P. chinensis, P. friedrichsthalianum, P. molle and P. quadrangularis were evaluated for resistance to fruit fly [Bactrocera dorsalis (Hendel)] and tea mosquito bug (TMB) [Helopeltis antonii (Sign.)], during 2002-04. Significant variations were recorded among species in their reaction to pests. Two species viz., P. chinensis and P. quadrangularis were resistant to fruit fly (<10% fruit damage) while P. quadrangularis was immune. Psidium. molle and P. cattleianum were resistant to tea mosquito bug. Pest incidence was correlated with fruit biochemical components viz., total soluble solids (TSS), total sugars, vitamin C and acidity. The TSS and total sugars were positively correlated with fruit fly infestation while acidity was negatively correlated. The TMB incidence did not exhibit significant correlation with any of these parameters

    There is a lack of spectrum due to the rising demand for sensing device communication and the inefficient use of the existing available spectrum. Through opportunistic access to licenced bands, which does not obstruct the primary sensory users (PU), it is feasible to enhance the inefficient use of the current sensor device frequency spectrum. Cognitive settings are a demanding environment in which to carry out tasks like sensor network routing and spectrum access since it is difficult to access channels due to the presence of PUs. The basic goal of the routing problem in sensor networks is to establish and maintain wireless sensor multihop paths between cognitive sensor nodes. The frequency to be used as well as the number of hops at each sensor node along the path must be determined for this assignment. In order to improve performance while using less energy, scientists suggested a unique adaptive cross-layer optimisation subcarrier distribution technique with the HOLSR protocol for wireless sensor nodes. Throughput and energy consumption parameters are used to analyse the sensor network architecture protocol that has been developed. The energy usage of the sensor nodes in the network has increased by 50%. The performance of the proposed HOLSR algorithm is assessed using the simulation results, and the results are contrasted with those of a conventional multicarrier (MC) system in terms of bit error rate and throughput

    The present study was carried out to determine the in vitro hepatoprotective activity of ethanolic extract from Eichhornia crassipes (EEEC) flowers using the CCl4-challenged BRL3A cell model. Hepatoprotective activity of EEEC (at concentrations of 50, 100 and 200 μg/mL) and standard drug silymarin (200 μg/mL) was evaluated against CCl4 induced toxicity using BRL3A cell line by measuring the cell viability, aspartate aminotransferase (AST), alanine aminotransaminase (ALT), lactate dehydrogenase (LDH) leakage, lipid peroxidation (LPO) and glutathione level (GSH). Treatment with CCl4 produced a significant decrease in cell viability. In addition, hepatotoxicity was revealed by increased hepatic marker enzymes like AST, ALT and LDH paralleled with elevated lipid peroxidation and decline in GSH levels. The toxicity induced by CCl4 in the BRL3A cells was significantly recovered by treatment with EEEC. The tested doses (100 and 200 μg/mL) significantly (P <0.01) reduced the CCl4 induced elevation of AST, ALT and LDH and also restored the altered biochemical parameters. These findings provide a basis for confirming the traditional uses of E. crassipes in treating liver ailments
